Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+          softmacro core, which is a fully-synthesizable functional model
+          described in Verilog-HDL.
+
+          The Mappi-I board was the first platform, which had been used
+          to port and develop a Linux system for the M32R processor.

+ * Semaphores are implemented using a two-way counter:
+ * The "count" variable is decremented for each process
+ * that tries to acquire the semaphore, while the "sleeping"
+ * variable is a count of such acquires.
+ *
+ * Notably, the inline "up()" and "down()" functions can
+ * efficiently test if they need to do any extra work (up
+ * needs to do something only if count was negative before
+ * the increment operation.
+ *
+ * "sleeping" and the contention routine ordering is protected
+ * by the spinlock in the semaphore's waitqueue head.
+ *
+ * Note that these functions are only called when there is
+ * contention on the lock, and as such all this is the
+ * "non-critical" part of the whole semaphore business. The
+ * critical part is the inline stuff in <asm/semaphore.h>
+ * where we want to avoid any extra jumps and calls.

+ * INET         An implementation of the TCP/IP protocol suite for the LINUX

+ *              Lots of code moved from tcp.c and ip.c; see those files

+ * Changes:     Ingo Molnar, converted csum_partial_copy() to 2.1 exception

+ *              Andi Kleen,  add zeroing on error
